3x3 · 1LLL
3x3 1LLL 10 12 algorithm
3x3 1LLL 10 12 algorithm: 13 turns, opening with y' R U. Case recognition, the complete sequence, and practical execution notes.
Solve this specific last-layer orientation and permutation in one sequence after completing the first two layers.
Recognize this starting position
In the inverse-derived training position, the upper-face color points upward at these corner positions: UBL. Upper edges with that color facing up: UF, UR. Reading each side’s top row left to right when facing that side gives F: B L U; R: L F U; B: F U R; L: B U U. The letters identify colors by their reference faces.
Execute the algorithm
y' R U Rw' U R U' M' U' R' U2 M U M'
The opening is y' R U; the final segment is M U M'. This version contains 13 face, wide, or slice turns and 1 whole-puzzle rotation.
